First Superbowl Ever to be Played Under LED Lighting: A new Era in Lighting
Steve Taranovich 1/28/2015 35 comments
Unlike the disastrous Superbowl XLVII in 2013, when the Metal Halide stadium lights went out at an inopportune moment, Ephesus LED Sports Lighting, a US-based company that manufactures high-output LED lighting solutions for challenging applications in the industrial and sporting markets, has supplied the Stadium with high performance LED stadium lights.
The Power of the Printed Word

The MIT Age Lab recently worked with Monotype Imaging in an investigation of effects of typeface on the demand of human-machine interactions during a simulated in-vehicle point-of-interest (POI) menu selection task. Their study showed that people could perform a menu selection task faster and with more accuracy depending upon the text type used as well as white text on a black background vs. the standard block text on a white background. Differences were clearly noted.
Voice, Wireless or Infrared Control?

One of the key themes throughout my tour of CES 2015 exhibits was the wireless of infrared control of the Smart Home. Using your Smart Phone or Tablet, exhibitors showed how you could easily control many functions in your home.
Latchup and its prevention in CMOS
Keith Sabine 1/14/2015 5 comments
Early CMOS processes suffered a reliability concern that became known as latchup. It resulted in circuits either malfunctioning or consuming excessive power, and could be either inherent in the design or triggered by voltage spikes on IO pads that could forward bias PN junctions they were connected to.
An AC Current Generator, Part 4

In parts 1 through 3 I described the construction of the transformer we needed to generate the 10Amps AC. We still had to drive the transformer.
Analog circuit bliss can be yours, with a modest investment
Analog Angle 1/12/2015 11 comments
You can experience the joys and depths of analog circuit design by reading some recent, and not-so-recent, books; they explore topologies, error sources, components, and will likely spark some creative thinking about solutions to real-world circuitry issues.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
